Instead, White is handed an excellent attacking opportunity, which he takes after completing his development, gaining a clear advantage by move 12. Black neglects his defense of the evil e-file and should have been punished for it on move 15, where the engines show White winning a piece. However, White loses his nerve and goes for two piece exchanges. The exchanges allow White to wreck Black's kingside pawn structure, but the disappearance of the attacking pieces and Black's extra pawn mean that the position is level. White makes some additional demonstrations on the kingside, but his decision to again exchange an attacking piece on move 21 leads eventually to the draw.
Again I am struck by the usefulness of analyzing your own games as an improvement practice. Had I been serious about this earlier in my career, it would have led more quickly to better performance. In this case, the neglect of the e-file should have led to a loss and meant that Black was happy to end up with a draw. My tendency to neglect this necessary defensive aspect of the position was evident in the previously analyzed game, but the lesson had not been learned.
